FS/AA vs FS/XX

[Tony Fagnilli]

I was checking out the entry lists for some of the NHRA national events and saw some guys entered in FS/XX. What's the difference between FS/ XX and FS/AA?

FS/XX is the class designation for the Factory Stock Showdown cars which run in their own separate eliminator. FS/AA is the designation for the cars that choose to run in Stock eliminator. The Factory Stock Showdown cars that don't qualify for the eliminator are not allowed to run in Stock eliminator. A FS/XX car can run in FS/AA by adjusting weight to meet the FS/AA weight break which is 5.50 - 5.99 lbs per factored HP. Conversely a FS/AA car can run in FS/XX by adjusting weight accordingly. The Factory Stock Showdown is contested at 8 National Events this year.

Thanks superfan. But, they are entered in stock, why are they not entered in the showdown?

For example. Cody Phillips is entered in FS/XX at Bristol, in stock. There is no FSS contested at this race. So why is he entered in stock as an XX car?

When he goes through tech, he will tech in as a FS/AA.

There was talk on here about different Shootout superchargers and maybe a few other things in a post, are they allowed in Stock eliminator?
